I just replaced my battery and it was running fine for a week and now I'm getting a drivetrain error. Do I need a scanner to find out why this is happening?
I have a 2014 i3 Rex. She just turned 10!🎂 Had a friend change the battery, new tires last year, Air filter, she looks brand new. So fun to drive. I wish I could have afford a bigger battery. Rex gets me by.
